Powkiddy X2 is a Low-End Nintendo Switch Lookalike

Powkiddy specializes in handheld gaming consoles, and if their latest Powkiddy X2 portable game console looks familiar, it’s because it looks just like a Nintendo Switch. But the comparison stops there. The NVIDIA processor is replaced by a quad-core Cortex-A7 processor, the display has a lower resolution, the controllers aren’t detachable, and unsurprisingly you can’t play any Nintendo Switch games. Powkiddy X2 specification: SoC – Quad-core Cortex-A7 processor @ 1.3 GHz (possibly Rockchip RK3128) System Memory – TBD Storage – TBD flash storage, MicroSD card slot Display – 7″ IPS display with 1024×600 resolution Video Output – Mini HDMI output Audio – 3.5mm audio jack; speaker(s); MP3/MP4 audio playback USB – 2x Micro USB port to connect external gamepads User input – 2x rockers, 2x D-PADs, select and start keys, function key, L&R; power & reset keys, volume control Battery – 3,000 mAh The console is said to come with 11 game console emulators to play retro games for the …

Rikomagic R6 Mini Projector Review – Part 2: Android 7.1

Rikomagic R6 Android Projector Review

We’ve already quickly checked out Rikomagic R6 mini projector in the first part of the review with an unboxing and first boot,  but now I’ve had more time to play with the device, so I’ll report about my experience. Android Launcher and Default Apps Here’s the launcher pre-installed in the projector. Media Center The Media Center app allows you to display images, play audio files as well as videos. It will show thumbnails of images present in the current folder… and as soon as you select one image in the folder it will start a slideshow with classic music playing the background. You’ll be able to see what it looks like in the video at the end of this review. Happy Cast It’s an app in Chinese, that apparently allows you to cast from other Chinese apps, but I have not used it. WiFi Display WiFi Display will be one of the most useful app, as it allows you to …

Linux 5.0 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linux 5.0 Changelog

Linus Torvalds has just released Linux 5.0: Ok, so the last week of the 5.0 release wasn’t entirely quiet, but it’s a lot smaller than rc8 was, and on the whole I’m happy that I delayed a week and did an rc8. It turns out that the actual patch that I talked about in the rc8 release wasn’t the worrisome bug I had thought: yes, we had an uninitialized variable, but the reason we hadn’t immediately noticed it due to a warning was that the way gcc works, the compiler had basically initialized it for us to the right value. So the same thing that caused not the lack of warning, also effectively meant that the fix was a no-op in practice. But hey, we had other bug fixes come in that actually did matter, and the uninitialized variable _could_ have been a problem with another compiler. Regardless – all is well that ends well. We have more than a …

KINGJIM Pomera DM200 Rockchip RK3128 Portable Mini Computer Can Run Debian

Ultra mobile portable computers (UMPC) are somewhat making a come back with products such as GPD Pocket 2 or DragonBox Pyra open source handheld computer.

By default, the device runs  a Linux OS with user interface in Japanese only, and is sold as a digital memo.

Linux 4.15 Release – Main Changes, Arm and MIPS Architectures

Linus Torvald has released Linux 4.15 last Sunday: After a release cycle that was unusual in so many (bad) ways, this last week was really pleasant. Quiet and small, and no last-minute panics, just small fixes for various issues. I never got a feeling that I’d need to extend things by yet another week, and 4.15 looks fine to me. Half the changes in the last week were misc driver stuff (gpu, input, networking) with the other half being a mix of networking, core kernel and arch updates (mainly x86). But all of it is tiny. So at least we had one good week. This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the middle of the cycle and not really gelling with our normal release cycle. The extra two weeks were obviously mainly due to that whole timing issue. Also, it is worth pointing out that it’s not like we’re “done” with …

Linux 4.13 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just announced the release of Linux 4.13 and a kidney stone…: So last week was actually somewhat eventful, but not enough to push me to delay 4.13. Most of the changes since rc7 are actually networking fixes, the bulk of them to various drivers. With apologies to the authors of said patches, they don’t look all that interesting (which is definitely exactly what you want just before a release). Details in the appended shortlog. Note that the shortlog below is obviously only since rc7 – the _full_4.13 log is much too big to post and nobody sane would read it. So if you’re interested in all the rest of it, get the git tree and limit the logs to the files you are interested in if you crave details. No, the excitement was largely in the mmu notification layer, where we had a fairly last-minute regression and some discussion about the problem. Lots of kudos to Jérôme …
